WhatsApp and nine
other ideas that were
snubbed before making
it big
From The Beatles to Harry Potter, Inspector Morse and Elvis, there are numerous brainwaves that first fell on deaf ears
WhatsApp founders Jan Koum and Brian Acton became overnight billionaires courtesy of Facebook when the social network giant bought their app.
But Facebook bosses should be kicking themselves after turning Acton down for a job in 2009.
At the time he took to Twitter saying: "Facebook turned me down.. looking forward to the next adventure."
And what an adventure followed - his next venture was WhatsApp, which shook up the world of messaging, turning users away from text messages and Facebook.
The service now has 450 million users and adds approximately a million new users a day.
